I have the huge Oakley ski bag.
Buy it, don't ask questions. It is the sickest bag ever made. I put my Bacons and Anthems in it and traveled on a train bus and a plane and everything was fine. The bag is burly as fuck, such good construction and it's a huge bag. You won't have to worry about fitting everything in it, you will have to worry about not going over a 50 lb. limit for planes.
I can fit 2 pairs of skis, 2 boots, 2 coats, and 2 pairs of pants in my bag + a bunch of other misc stuff, it goes over the limit but if you pack it right you will be fine, you might wanna put the boots in a different bag though depending on what else you put in it.
Any other questions just send me a pm or whatever.
